Seminoe State Park

Seminoe State Park is often referred to as the ‘true treasure of Wyoming’ with its wide open water and friendly atmosphere. It’s located in Carbon County 35 miles north of the small town of Sinclair and 75 miles west of Caspar. This Wyoming state park lies on the northwest side of the Seminoe Reservoir at the base of the Seminoe Mountains and comprises some 1,639 acres of land around 19,000 acres of water with mountains as high as 6,460 feet. The park was established in 1965 about 45 years after the Seminoe Dam was built. Come visit this ‘oasis in the desert’ and discover for yourself all that this beautiful area has to offer. Bring the entire family and have a pleasant time camping, hiking, fishing, boating, swimming, sightseeing and exploring here in rustic Wyoming.

Activities

Sinclair is considered the gateway to several local recreational areas – Historic Sinclair, Parco/Sinclair Museum, Seminoe State Park and Sinclair Golf Club. Seminoe State Park is probably the prettiest and most special of them all. Not only is it an ideal day spot to set up camp or just visit for the day, but it is also thought highly of as a wedding and special event venue. So much so that there are several group sites that can be reserved for such special events. Here are the other popular activities that you can do at Seminoe State Park:

Boating at Seminoe State Park

The Seminoe Reservoir is 21 miles long and fed by 2 rivers, the North Platte River and the Medicine Bow River, meaning that there is a lot of space for boating (as well as other water activities). And it’s very windy on the reservoir making it ideal for wind powered boats. There are boat docks and ramps at both the North and South Hills areas as well as private ramps at Seminoe Boat Club and Medicine Bow Boat Ramp. Seminoe Boat Club is privately owned and also has a restaurant, general store and campground.

Swimming at Seminoe State Park

The large reservoir ensures many opportunities for swimming (during the warmer months anyway). All 3 campgrounds have beach areas but the best one is at Sunshine Beach. Sandy Mountain Day Use Area also has a nice sandy beach and 2 picnic areas.

Fishing at Seminoe State Park

The reservoir is regularly stocked with rainbow and cutthroat trout making this an angler’s dream spot to fish. You can also catch walleye and brown trout here. Pick up a license on your way to the park or get one at the Seminoe Boat Club.
